1.开始当然是要stop()第一帧；
2.把所有需要导入的文件路径放在数组中，（文件格式只包括swf和jpg）把需要显示层级高的放在数组的后面。如下：
var arr_swf = new Array();
arr_swf[0] = "LeftGuy.swf";
arr_swf[1] = "RightBg.swf";
arr_swf[2] = "RightTitle.swf";
arr_swf[3] = "RightBorder.swf";
arr_swf[4] = "Menu.swf";
arr_swf[5] = "Banner.swf";
arr_swf[6] = "SwitchGuy.swf";
arr_swf[7] = "ToHome.swf";
_root.cur_swf = 0; //当前所指向的arr_swf数组的游标
3.用MovieClipLoader类来完成主要函数
function load_swf(str_swf, int_level) {
var my_mcl = new MovieClipLoader();
myListener = new Object();
myListener.onLoadStart = function(target_mc) {
var loadProgress = my_mcl.getProgress(target_mc);
_root.mc_loading.loading.text = Math.round(100*loadProgress.bytesLoaded/loadProgress.bytesTotal)+"% ("+str_swf+")";
};
myListener.onLoadProgress = function(target_mc, loadedBytes, totalBytes) {
trace(Math.round(100*loadedBytes/totalBytes)+"% ("+str_swf+")");
_root.mc_loading.loading.text = Math.round(100*loadedBytes/totalBytes)+"% ("+str_swf+")";
};
myListener.onLoadComplete = function(target_mc) {
var loadProgress = my_mcl.getProgress(target_mc);
_root.mc_loading.loading.text = Math.round(100*loadProgress.bytesLoaded/loadProgress.bytesTotal)+"% ("+str_swf+")";
if (int_level<8) {
_root.cur_swf++;
load_swf(arr_swf[_root.cur_swf], _root.cur_swf+1);
} else {
_root.mc_loading._visible = false;
_root.gotoAndStop("start");
}
};
myListener.onLoadInit = function(target_mc) {
target_mc.gotoAndStop(1);
};
myListener.onLoadError = function(target_mc, errorCode) {
_root.mc_loading.loading.text = "错误,文件无法加载 ("+str_swf+")";
};
my_mcl.addListener(myListener);
my_mcl.loadClip(str_swf, int_level);
}
}
其中 onLoadComplete 事件用了一个递归，当数组里的文件没有被下载完全时，就会一直调用这个函数；反之，退出广播，跳入到下一帧。
4.最后，上面的是函数的定义，当然还要调用它才能运行
load_swf(arr_swf[_root.cur_swf], _root.cur_swf+1);
